摘要
本文通过1988—1990三年研究,测定了大豆花荚期豆田蚜量与大豆产量的关系,并依据这种关系及目前大豆商品生产状况提出了新的豆田蚜虫防治指标。
The relation between population density of aphid during flowering season and soybean yield was determined in 1988-1990. Based on the three year result, the control threshold of aphid for different level of soybean yield was proposed.
